80691203 divided by 36 
The aim is to understand the frequency of 36 in 80691203.

Let's proceed to step 1:
When dividing 8 by 36, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 36

Step 2:
The number 36 fits into 80 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 72 from 80 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 36

On to step 3:
If we divide 86 by 36, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtracting 72 from 86 leaves us with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 36

Going ahead to step 4:
When dividing 149 by 36, we get 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 224.0
Subtracting 144 from 149 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 36

On to step 5:
When dividing 51 by 36, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 2241.0
Deduct 36 from 51 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 36

Going ahead to step 6:
152 divided by 36 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 22414.0
If we take 144 away from 152, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 36

Going ahead to step 7:
When dividing 80 by 36, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 224142.0
Deduct 72 from 80 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 36

Step 8:
83 divided by 36 is 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2241422.0
If we take 72 away from 83, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 36, we get 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 2241422.3
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
When dividing 20 by 36, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2241422.3
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
36 goes into 200 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2241422.305
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
If we divide 200 by 36, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2241422.3055
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 2241422.3055, and the remainder is 0.0002.
